Chronic myeloid leukemia (CML) is characterized by the Philadelphia translocation that fuses BCR sequences from chromosome 22 upstream of the ABL gene on chromosome 9. The chimerical Bcr-Abl protein expressed by CML cells has constitutive tyrosine kinase activity, which is essential for the pathogenesis of the disease. Imatinib, an ATP-competitive selective inhibitor of Bcr-Abl, has unprecedented efficacy for the treatment of CML. Most patients with early stage disease achieve durable complete hematological and complete cytogenetic remissions, with minimal toxicity. In contrast, responses are less stable in patients with advanced CML. This review highlights the pathogenesis of CML, its clinical features, and the development of imatinib as a specific molecularly targeted therapy. Aspects of disease monitoring and side effects are covered as well as resistance to imatinib and strategies to overcome resistance, such as alternative signal transduction inhibitors and drug combinations. Perspectives for further development are also discussed.
What tyrosine kinase, involved in a Philadelphia- chromosome positive chronic myelogenous leukemia, is the target of Imatinib (Gleevec)?

Carpal tunnel syndrome is a complex of symptoms as a result of compression of the median nerve in the carpal tunnel. As nerve entrapment induces impairment of somatic fibres followed by clinical symptoms and signs of the syndrome, one can assume that sympathetic fibres are involved too. Results of studies focused on this problem show presence of sympathetic symptoms in about half of patients, including Raynaud phenomenon, blanching of hands, painful swelling of fingers, dry or excessive sweating of palms. Activity of sympathetic system can be investigated by means of sympathetic skin response and vasomotor response. Eight papers presenting the results of sympathetic skin response from median nerve in carpal tunnel syndrome were analysed. Results of 4 studies showed decreased sympathetic activity, in 2 findings were equivocal and 2 studies failed to reveal any abnormalities. The following variables were considered in the interpretation of sympathetic skin response curve: amplitude, latency and area under the chart, each of them having limited diagnostic value due to inter-and intrasubject variation of these parameters. Vasomotor response was investigated in 2 studies by means of Doppler ultrasound flow examination in digital arteries. Results of both studies showed decreased vasomotor response in carpal tunnel syndrome. The review of current knowledge on sympathetic impairment in carpal tunnel syndrome fails to provide a definitive determination of its range and clinical consequences. It confirms, however, that routine examination of sympathetic disturbances is unnecessary due to their minor clinical significance.
